How do I add my website to Matomo for getting the accurate stats?

I am used to google analytics and don’t use any other app or software for knowing the performance of my websites. I have got 3 questions.

  1. How accurate Matomo results are?
  2. How do we connect our website with Matomo to look after the performance of our website.
  3. Are we allowed to add more than 1 website to Matomo or we can just get the analysis of just one website?
    You can visit the website which is connected with the analytics.
    Thanks to all.

As Matomo can track 100% of visits it can be more accurate than Google (that can encounter some difficulties with user cookie opt-out and also that doesn’t take all visits into account in case of high volumes)
